Integra Cooling System Bleed Instructions
Bleeding the coolant system after taking it apart removes air from the system. Some part manufacturers refuse to warrant a new radiator if the system is not properly bled and purged of air before using their new parts. Here are some instances when bleeding the engine cooling system is a good idea.
When to Bleed Integra Coolant System
- Coolant flush every 30,000 miles
- Radiator replacement or upgrade
- New thermostat
To bleed your Integra’s coolant system, top off the coolant and follow these steps:
- Warm up the car to normal operating temperature with no radiator cap or radiator cap closed to first stop position that allows steam to bleed out. Some radiators have a bleed bolt near the cap that you can loosen to bleed air out.
- Watch coolant drop when thermostat opens and add more coolant to system.
- Wait for bubbles to stop and coolant to begin bleeding out of the radiator
- Turn off the car and top off the coolant to the fill line.
